Cottonseed, which formerly was a nuisance, is now a crop second only in value to the cotton fiber itself. The cellulose of straw is now being worked up into wallboard and building material. Up to the present our corn fields have produced only a single crop, corn, to repay the farmer for his toil and capital outlay. The corn- stalks, heretofore largely waste, are now being made into writing paper and other papers of excellent quality, while from the corncobs come furfural, which may supplement or supersede gasoline in our motor cars and gas engines. Bagasse, the waste of sugarcane, makes a standard wallboard. How revolutionary inventions for farming have become is seen in the new Mason Process of drying alfalfa. This invention permits “making hay while it rains” as well as while the sun shines, and makes practicable the growing of this main forage crop in the states of heavy rainfall in the East, where the chief dairy herds are located. It is reducing a dairy system from the need of devoting ten to one hundred acres to pasture per cow to a system whereby three animals can be kept in prime condition on one acre. In his forthcoming book, The Great Food Problem and Its Solution, Dr. Orrin W. Willcox, calculates that the earth’s population may increase in almost unbelievable numbers through application of recently discovered laws of plant growth, chemi- cal fertilization, and transmutation of food proper- ties. These, combined with selection of plants with
